Finely powdered commercial sulfur does not inhibit appreciably the growth of spores of the white mold, Penicillium sp. and Aspergillus sp. Diethyl sulfite in concentration of 7.38 grams/liter is found to be toxic to the spores of the white mold, and its toxicity is markedly increased by addition of lactic acid. Infrared absorption spectra studies of mixtures of sodium metabisulfite and sodium lactate indicate no interaction between the sulfite and the lactate ions. The use of a solution of lactic acid and sodium bisulfite on heating silage in the silo gave considerable reduction in the temperature.
